Abstract: A distributor for liquids has a base member having an intake and at least two outlets. At least one branch member is connected to one of the at least two outlets in a position that is changeable relative to the base member. The at least one branch member has an outlet opening. A distributor kit has a distributor, a closure element for closing one of the at least two outlets of the base member of the distributor, and branch elements for each one the outlets that is not closed off by the closure element.

Abstract: A water pump for bodies of water such as ponds, aquariums, or fountains containing suspended particles has a housing with a pump housing part provided with an intake opening and an exit opening, in which housing part an impeller with a shaft is rotatably supported, and a motor housing part in which an electric motor is received. As an improvement, an electronically commutated motor is used and the pump has a power input as well as power and control electronics for the motor having an operating state detection device with speed detection, processor and data storage device. The processor can control an interrupt switch between the power input and the motor. In the data storage device certain characteristic lines in regard to normal operating states can be stored.

Abstract: A pump arrangement for bodies of water or containers with water subject to biological influences has at least one water pump and a control device controlling the speed of the water pump. At least one temperature sensor measures the water temperature and provides signals of the measured water temperature. The signals are processed in the control device and the speed of the pump water is controlled by the control device based on the signals.

Abstract: A pump for ponds, aquariums or similar facilities has a synchronous motor arranged within a motor housing. The motor has a permanent-magnet rotor and a stator, wherein the rotor is separated from the stator by an inner wall of the motor housing. A housing part is provided that forms a flow channel. The pump has a removable mounting flange for rotatably securing the rotor. The housing part is detachably mounted on the flange by a fastening device. The mounting flange seals a can forming the inner wall relative to the remaining motor housing and secures a bearing bracket serving for supporting the rotor.
